In 2017 Ghana carried out an impact assessment of its onchocerciasis programme. The findings from that assessment showed that seroprevalence in children less than 10 years ranged between 0 and 5% in most of the surveyed communities. However, one community, Ottu-Kwanware recorded a seroprevalence of 38%, the highest in that study and in recent years. The sample size was, however, too small raising the issue of how widely to interpret this finding. Thus, there is the need to carry out a more thorough investigation to understand the nature of onchocerciasis transmission in the Wenchi municipal area.
The current study employs parasitological and entomological surveys to understand the extent of onchocerciasis transmission in and around Kwanware community. This study will also employ household treatment coverage surveys to understand the reasons for what appears to be sustained transmission in the Wenchi municipal, specifically around Kwanware and neighbouring breeding sites.
